### Please describe the problem.

Thanks for the improvements in Windows long file support but it turns out that Git-annex
commit 54ad1b4cf doesn't quite compile on Windows without a small fix to Remote.Git and
Utility.DirWatcher.Win32Notify regarding imports.

### What steps will reproduce the problem?

`stack setup && stack build`

### What version of git-annex are you using? On what operating system?

A successful build that passes the testsuite on Windows is achieved with the patch below.

Windows 10 version 22H2 (build 19045.2486), 64 bit.

This then compiled cleanly and completed the test suite ok.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Git Annex is great. I use it several times a week with my multigigabyte backups, where it gives structure to my image-based backup routines, so you could say I'm a believer. :)
